Yes, just took you a screenshot

I'm pretty sure I can get the 500 by using my 2 heart, or maybe i'm totally wrong XD

The 4 that you see was just after I finished installing it. It was still downloading block. About the public or the test, I supose i'm on the public network. I simply did the bitcoin -server, and started the poclbm. While I was reading, I heard about a shared pool. Is it really that good ? If you have any info you can help me don't hesitate, I'm open to anything =) Btw i'm on irc ( Malouin ) presently if you wanna talk !

I see

Thanks for the info and for the help david, I really appreciate it. If you want me to do some test or help you on something, don't hesitate.

The miner should display 'bitcoin is downloading blocks...' until all blocks are downloaded. Please test. This was added in the SVN 163 patched client.

David, I removed usage of vectors. So the '-w 128' is not relevant anymore. Of course you can grab the vectors version from git and use it like before. It is really difficult to optimize for all possible devices. Current version is kind of best for all.

[m0mchil]

From now on I'll post latest versions only in the initial post of this thread.

[xxmalouinxx]

Tried the -f 35 and -w 128. I get around 270m khash/s. And yes, I can load 2 separate poclbm, using device 1 and device 2, both are doing around 268m khash/s. Total of 536m khash/s.

And yes, it display the bitcoin is downloading blocks... Thanks !

Update : I Oc'ed my 5970 GPU clock from 725 MHZ to 800 MHZ and my memory clock from 1000 to 1305MHZ.

I'm now at 295m on each heart, total of 590m. Everything seem to be fine, I will let you know about futur update and how much I can get with the 5970.

590 mhps!!!

[xxmalouinxx]

hehehe thanks guys =P

I was speaking with Art on irc today, and my next step will be to OC my 5970 from 800 to 910mhz. I should reach the 320mhash/s on each heart, which mean a big total of 640mhash/s.

I restarted my client at 15h30 EAST time, and will stop it tomorrow at the same time. It gonna give me some data to work on. After that, i'm going to OC it at 910mhz and see the result and report here with some screenshots.

bethel, what are 5870s showing at stock frequency (850 MHz)? Perhaps one of the cards throttles down?

Latest version has new parameter, -w, to set work group size. I have best results on 5770 with -w 128 -f 35.

Latest py2exe version is http://github.com/downloads/m0mchil/poclbm/poclbm.7z

Sorry for the late reply, I have been away for a while.

I found my problem and it was so simple it is silly. I had not yet enabled the -frames switch to crunch faster. I still don't know why one card was faster without the switch but they are about equal now.

As for the mhash @ 850mhz I get about 265mhps.

xxmalouinxx, what OS, SDK, and driver version are you on?

I can't seem to get my two cards to both run at the same time under Windows 7. Any hints?

[xxmalouinxx]

Windows 7 Ultimate / ATI SDK 2.2 for Win7 64 / Catalyst 10.7

I got a radeon 5970, so I don't have 2 cards, but 2 hearts on it. Art got 4 cards on 1 motherboard doing this, I'm gonna ask him when I see him.

Update :

Here's a screenshot of my last setting

640mhash/s - radeon 5970 870mhz/1305mhz - temp : 83c

Presently it run fine, but i'm not sure it gonna be stable, gonna update here if I have any news.

I want it!

incredible hashes/sec are incredible
do you think a Radeon 5970 would work fine with linux ?

[fergalish]

core i7 quad, nvidia GT240, 64bit ubuntu 10.04

CPU: 7000 khps
GPU: 20000 khps

Should I be getting more?  I have python 2.6.5 installed.

[xxmalouinxx]

Davout : Yea it should work without any problem on linux. ArtForz actually use that.

Fergalish : the Nvidia GT240 got 385 Gflops, the radeon 5970 got 4640. If we base it on the fact that the 5970 got 230 000khash/s per core without being OC, it should be around 20 000 khash/s yes.

Is poclbm.py supposed to use 100% CPU, and increase CPU usage of Xorg quite a bit as well?

Code:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
 4885 sturle    20   0  420m  56m  26m S  264  0.7  53:15.06 bitcoin            
 5522 sturle    20   0  231m  63m  24m S   97  0.8   9:44.01 poclbm.py          
14130 root      20   0  491m 174m 122m S   27  2.2  12:25.19 Xorg               

I get about 11500 khash/s maximum from poclbm.py, which is the same I get from bitcoin when running on all 4 CPU cores.  While poclbm.py is running, hash production from bitcoin is reduced to about 8k.  Is this normal?  Production from poclbm.py decreases if I reduce it's CPU share, e.g. by niceing it.

GPU is some ATI HD 5400 series.

I think it's a really good thing that such a client gets public, it decreases the chance that the blockchain gets overtaken by NSA XD

compared to my GTX260 which gets ~37.000 stock (575core/1240shader) and up to 45.000 oc'd (685/1480),
you should be ok with 20.000.

gonna run it on a radeon 5850 as soon as it arrives, should be by tomorrow.
hopefully i'll get some more outof that.
